Benefits of technology

[0018]In this way, it is possible to attach the first and second components to the electronic apparatus and thereby contribute to an improvement in the performance of the electronic apparatus. If the first and second components are battery packs, two battery packs of the same shape can be attached to the electronic apparatus. When one of the batteries has run down, the electronic apparatus may be operated with the other battery, or the capacity of the two batteries may be adapted to a desired operation of the electronic apparatus.
[0019]Because two battery packs of the same shape can be attached to the electronic apparatus, the development cost of battery packs is lower. Therefore, battery packs having greater capacity with the same shape can be developed at relatively low cost so that batteries may have longer life than before or a use may select, in combination, a suitable weight and capacity for the battery as the user desires. It is thus possible to easily realize a battery pack of greater capacity which achieves a suitable combination of weight and capacity. Attachment to an electronic apparatus is also simplified.

Problems solved by technology

However, miniaturization of the battery itself is also required, so there is a case in which replacement of the battery is necessary depending upon the relationship between the capacity, the weight and the volume of the battery.
If the battery is accommodated in the apparatus body, the battery cannot be readily replaced.
In the information processing apparatus including the internal and external batteries, however, when the built-in battery has run down, it is not easy to remove it for recharging.
Thus, two kinds of battery packs, that is, a built-in battery pack and an external battery pack, must be provided, which in turn requires two types of molds for molding battery packs with resin, which increases the cost of development of battery packs.

first embodiment

[0046]FIGS. 1 to 7 show an electronic apparatus according to the present invention. FIGS. 1 and 2 are views showing the electronic apparatus (portable type information processing apparatus) 10 constructed as a notebook type personal computer. The electronic apparatus 10 has a part 14 including a keyboard 12 and another part 18 pivotally attached to the part 14 including the keyboard 12 and including a display 16. The part 14 including the keyboard 12 is referred to as an apparatus body, and includes electronic components under the keyboard 12.

[0047]FIG. 4 shows the part 14 including the keyboard 12 in the state in which the keyboard 12 is removed, with the part 18 including the display 16 omitted. A printed circuit board 20, for example, is disposed in the part 14 including the keyboard 12. The keyboard 12 and the display 16 are controlled by the electronic components provided on the printed circuit board 20.

[0048]The part 14 including the keyboard 12 is formed in a generally rectan...

third embodiment

[0070]FIG. 15 is a cross sectional view showing an electronic apparatus according to the present invention. The general construction of the electronic apparatus (information processing apparatus) 10 is the same as that shown in FIGS. 1 and 2. The electronic apparatus 10 comprises a part 14 including a keyboard 12, another part 18 including a display 16, a first battery pack 22 and a second battery pack 24 (see FIGS. 1 and 2).

[0071]In this embodiment, the battery pack 22 (24) is constructed such that a lithium cell 64 is molded with and covered by, resin 66. The lithium cell 64 is connected to the terminals 38x and 38y of the connector 38. The battery pack 22 (24) may include a control circuit connected to the lithium cell 64.

[0072]The part 14 including the keyboard 12 includes a connector 30 and a mechanical connection means 32. The mechanical connection means 32 include a threaded hole to be engaged with a screw 40. The connector 30 includes terminals 30x and 30y which are biased o...

fourth embodiment

[0073]FIG. 16 is a view showing an electronic apparatus according to the present invention. The electronic apparatus (information processing apparatus) 10 comprises a part 14 including a keyboard 12 and another part 18 including a display 16. The part 14 including the keyboard 12 includes a first attachment portion 26 and a second attachment portion 28 (see FIG. 2). A connector box 72 is attached to the front of the part 14 including the keyboard 12 at the first attachment portion 26, and a battery pack 24 is attached to the rear of the part 14 including the keyboard 12 at the second attachment portion 28. The connector box 72 includes a connector 38 to be fitted to a connector 30 of the first attachment portion 26, as well as a plurality of connectors 74a, 74b, 74c and 74d. In FIG. 16, a mouse 76 is attached to the connector 74d.

Abstract

An electronic apparatus has a first attachment portion to which a first component can be attached to the front of the apparatus body, and a second attachment portion which has a substantially same construction as the first attachment portion and to which a second component can be attached to the rear of the apparatus body. Thus, the first component and the second component can be attached the electronic apparatus to thereby improve the performance of the electronic apparatus. When the first and second components are battery packs, two battery packs of the same shape can be attached to the electronic apparatus.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of PCT / JP99 / 01164 filed March 10, 1999.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to an electronic apparatus. More particularly, the present invention relates to a battery support structure for a portable type information processing apparatus such as a notebook type personal computer.[0004]2. Description of the Related Art[0005]Recently, electronic information processing apparatuses have become increasingly small and light-weight so as to be suitable for use as portable type information processing apparatuses. A portable type information processing apparatus usually includes a battery that has a relatively large capacity and the battery is usually accommodated in the apparatus body since replacement of a battery is seldom required. However, miniaturization of the battery itself is also required, so there is a case in which replacement of the battery is n...
